If im 155cm tall hwo big should my snowboard be

Remember, the length of ur board is more dependent on ur weight, ability, style of riding & preference than ur height.

Most park riders like a smaller board for its easier manuverability & lighter weight. Most freeriders like longer boards for their stability. Go to a good board shop & ask the guys there what they think. Do not forget about ur shoe size. This is important because if ur board is too narrow ur toes & heels will drag & if it is too wide it will be harder to turn. Check out some of the links l gave u in ur other question, l answered questions like this in more detail there.

Totally agree with the previous answer. l have heard that a good rule of thumb is that if u stand next to ur board it should be between ur chin & ur nose, so it may give u a good starting point. However in the end ur weight & ur riding style r going to be the most important thing. One thing u might want to do is to find a day when u can demo a few different sized boards or a rental shop might let u try a few different board lengths over the course of the day.

Just for reference l am 5'5'' (165cm), 150lbs & currently ride a 155cm board. l guess l like fives!

l agree with the first guy. if u want to go faster u should get a longer board. if u want to be able to do tricks u should get a shorter board. l think u should get maybe a 145 cm

about 151cm
